The weld characterization of modified 9Cr–1Mo–V (P91) steel bead-on-plate autogenously weld (without filler metal) samples of N-TIG, A-TIG (with TiO 2 ), FBTIG (with TiO 2 ) and FZ-TIG (TiO 2 and ZnO) activated flux system revealed varied
weld dimensions and depth-enhancing characteristics. A further investigation into
